Collective vibrations in atomic nuclei are studied, assuming a time- dependent nuclear well potential. The collective frequencies (and the collective parameters B lambda and C lambda ) are obtained by imposing the condition of time-independence on the expectation value of the energy. The calculations are carried through without the use of adiabatic approximation. For some closed- shell nuclei it is found that the lowest vibrational state should not be of the quadrupole type. The life-times of vibrational states are also calculated. The related problem of static deformations of a finite well potential is discussed. Some numerical results for the quadrupole and octupole vibrations in O/sup 16/ and the quadrupole vibration in Si/sup 28/ are given. (auth)
